Discoid lupus erythematosis, or DLE, is a chronic skin disorder, involving the face, scalp, ears and neck. DLE is different from systemic lupus erythematosus. SLE is a connective-tissue disease that affects many different organs. In generalized DLE, the skin on the arms and chest are affected. Discoid lupus advances to systemic lupus erythematosis in about 1 in 20 persons. DLE has its peak occurrence in women in their late 20's, but can affect adults of both sexes.

Signs and Symptoms of Lupus Erythematosus, Discoid
DLE produces plaques on the skin. They appear red and are raised with clearly defined borders. They generally are in the range of 1-4 cm. in diameter. The most common location for these plaques to develop is on the cheeks and jaw line. When two lesions appear on either side of the nose, a butterfly lesion may develop, similar to that seen in systemic lupus erythematosis. Sometimes, these plaques will develop on the scalp. When they do, there may produce localized patches of hair loss. Frequently, scarring of the scalp or skin occurs as the lesions heal.
